Question

During the extraction of metals, electrolytic refining is used to obtain pure metals.

a) Name the cathode and anode for the refining of silver in this process.

b) Suggest a suitable electrolyte.

c) In this electrolytic cell, where do we get pure silver after passing electric current.

Answer 1

a) Cathode: strip of pure silver metal
    Anode: strip of impure silver metal

b) Electrolyte to be used should be water soluble salt of the metal to be refined.
Electrolyte in this case should be Silver Sulphate [Ag2SO4].

c) Pure silver is obtained on Cathode.

HOPE THIS HELPS YOU!!!

Answer 2

✨✔️HERE IS YOUR ANSWER....

✨REFINING OF METALS....

IN THIS PROCESS IMPURE METAL IS MADE THE ANODE AND A THIN STRIP OF PURE METAL IS MADE OF CATHODE. ON PASSING THE CURRENT THROUGH THE ELECTROLYTE, THE PURE METAL FROM THE ANODE DISSOLVES INTO THE ELECTROLYTE. AN EQUIVALENT AMOUNT OF PURE METAL FROM THE ELECTROLYTE IS DEPOSITED ON CATHODE. THE SOLUBLE IMPURITIES GO. INTO THE SOLUTION, WHEREAS THE INSOLUBLE IMPURITIES SETTLE DOWN AT THE BOTTOM OF THE ANODE AND ARE KNOWN AS ANODE MUD.

Electrolyte:- A solution of metal salt is used as an Electrolyte.

(a) Impure silver in anode and pure silver in cathode.

(c) After refining we get pure metal in Cathode
